Is Nickel Magnetic? - UMD
It may be that the Nickel (Ni) in the nickel coin somehow disrupts the electrical currents. This seems possible since adding Nickel (Ni) to Iron, Carbon, and Chromium a form of stainless steel is created that is not magnetic even though it contains Iron. But dimes and quarters have Nickel as well, just less.

Magnetic Properties of Copper-Nickel Alloys
The magnetic susceptibility of alloys of copper and nickel in proportions ranging from 0.1 to 70 percent nickel have been studied. X-ray photographs of the alloys show that they are a homogeneous mixture of the copper and nickel crystals. Although copper is only weakly diamagnetic it requires 0.8 or 0.9 percent nickel to neutralize this diamagnetic effect and 56 percent nickel is required ...

Ferromagnetic materials. The most important class of magnetic materials is the ferromagnets: iron, nickel, cobalt and manganese, or their compounds (and a few more exotic ones as well).The magnetization curve looks very different to that of a diamagnetic or paramagnetic material. We might note in passing that although pure manganese is not ferromagnetic the name of that element shares a …
